Abstract
Liver cirrhosis is considered the most common cause of portal vein
thrombosis due to the defective synthetic function of the liver and stagnation
of blood flow. Added to that, the occurrence of HCC in cirrhotic patient may
lead to malignant PVT as well. Other causes may contribute to thrombosis
formation in the portal vein that could be benign such as thrompophilia and
post splenectomy or malignant because of the state of hypercoagulability like
cholangiocarcinoma or cancer pancreas.
In order to diagnose portal vein thrombosis, radiological demonstration
with color Doppler is the first choice. Further assessment with another imaging
modalities like CT or MRI are usually implemented for better visualization
and classification of the thrombus nature and extent.
